Clinical trial of atmospheric oxygen breathing during radiotherapy for cancer of the oropharynx.

A randomized clinical trial of atmospheric oxygen breathing during radiotherapy of advanced cancer of the tonsillar region has been conducted. In order to achieve a high level of inspired oxygen, a closed system with a "head tent" was used. Over 2 years after treatment, 30 percent of the oxygen patients survived without evidence of disease compared to 17 percent in the control group.
